The positions containing this symbol must all be in different rows and columns, and furthermore the other symbol in these positions must all be distinct.

Extensions of mutually orthogonal Latin squares to the quantum domain have been studied since 2017. In these designs, instead of the uniqueness of symbols, the elements of an array are quantum states that must be orthogonal to each other in rows and columns. In 2021, an Indian-Polish team of

However, no set of three MOLS(10) has ever been found even though many researchers have attempted to discover such a set. 714:) found an array of quantum states that provides an example of mutually orthogonal quantum Latin squares of size 6; or, equivalently, an arrangement of 36 officers that are entangled. This setup solves a generalization of the 36 Euler's officers problem, as well as provides a new 704:

in 1725. The problem was to take all aces, kings, queens and jacks from a standard deck of cards, and arrange them in a 4 x 4 grid such that each row and each column contained all four suits as well as one of each face value. This problem has several solutions.
58:, which ensures that independent variables are truly independent with no hidden confounding correlations. "Orthogonal" is thus synonymous with "independent" in that knowing one variable's value gives no further information about another variable's likely value. 1743:
In the examples of MOLS given so far, the same alphabet (symbol set) has been used for each square, but this is not necessary as the Graeco-Latin squares show. In fact, totally different symbol sets can be used for each square of the set of MOLS. For example,
539:
For each of the two solutions, 24×24 = 576 solutions can be derived by permuting the four suits and the four face values, independently. No permutation will convert the two solutions into each other, because suits and face values are different.

For example, the OA(5,4) in the above section can be used to construct a (5,4)-net (an affine plane of order 4). The points on each line are given by (each row below is a parallel class of lines):

The term "order" used here for MOLSs, affine planes and projective planes is defined differently in each setting, but these definitions are coordinated so that the numerical value is the same.

A common variant of this problem was to arrange the 16 cards so that, in addition to the row and column constraints, each diagonal contains all four face values and all four suits as well.
